How heavy metal pollution can affect land

The creation of good topsoil is not that difficult. Firstly, you need to have decent organic additives like decayed vegetable and fruit matter buried beneath it to provide good nutrients. Secondly, you need a decent mix of rain and sun to moisten and warm it in equal measure. Once you have a suitably good dark red or dark brown coloured crumbly mix you are ready to start growing some decent size plants and crops.

However, with the introduction of foreign contaminants, this job becomes harder. The hardiness of soil can be easily compromised with unpleasant substances like heavy metals, for example. What exactly are these heavy metals, and where do they come from? If you have them in your soil, it is a good idea to give the Remediation Contractors a call as soon as you can to provide a solution.

The name heavy metals are quite misleading. In all cases, they are metals but not in a weight sense. For example, one of the most common and dangerous, if ingested in large quantities, is Mercury. This is a liquid metal, but it is widely used in various applications. It is very present in fish, and if large concentrations of it get into the soil, it can have a hugely adverse effect on plant growth and human health. Others are heavy. Lead, for example, is a peculiar actual heavy metal, whereas Zinc, which is used in the food canning industry, is in between.
